Overview

Spatiotemporal analysis reveals that wildlife imports elevate disease emergence in countries worldwide, highlighting the critical need for import biosecurity.

Key Points

To quantitatively evaluate how international wildlife trade volumes influence the occurrence, frequency, and extreme outbreak events of zoonotic emerging infectious diseases globally.
Analyzed country-level annual zoonotic emerging infectious disease data from 1975 to 2013 across global jurisdictions.
Implemented a Bayesian zero-inflated negative binomial spatiotemporal model integrated with extreme value theory, adjusting for reporting bias and national surveillance capacity.
Wildlife import volume significantly increases the probability of zoonotic emerging infectious disease occurrence and extreme outbreak events, though it shows no significant association with overall outbreak frequency.
Wildlife export volume demonstrates no significant relationship with disease occurrence or frequency and exhibits a substantially weaker effect on extreme events.
Mammalian species richness and national socioeconomic indicators display complex associations with disease patterns, mediated by the effectiveness of local surveillance systems.
